Google's doodles are an outlet for the company's playful urges. And, even though they've become all too common, the redesigns still manage to pack the odd surprise. Take today's offering, which resembles New York's iconic street graffiti. But, that's not all, click the pulsing play icon at its centre, and the logo transforms into an interactive turntable. Now, you can play DJ, spinning a bunch of records that were instrumental to the creation of hip-hop. An accompanying video tutorial boasts narration from graffiti artist and TV presenter Fab 5 Freddy.
